In the U.S. the Coast Guard and industry collect AIS data, which can also be used for a variety of coastal planning purposes. NOAA and BOEM have worked jointly to re-task and make available some of the most important records from the U.S. Coast Guard's national network of AIS receivers. This dataset represents annual vessel transit counts summarized at a 100 m by 100 m geographic area. A single transit is counted each time a vessel track passes through, starts, or stops within a 100 m grid cell.", "summary": "AIS Vessel Transit Counts 2021", "title": "AISVesselTransitCounts2021", "tags": [ "coastal", "ocean", "planning" ], "type": "Map Service", "typeKeywords": [ "Data", "Service", "Map Service", "ArcGIS Server" ], "thumbnail": "thumbnail/thumbnail.png", "url": "", "extent": [ [ -173.475189293328, 13.8601640025776 ], [ -60.0026975492023, 51.7073267496894 ] ], "minScale": 0, "maxScale": 1.7976931348623157E308, "spatialReference": "WGS_1984_Web_Mercator_Auxiliary_Sphere", "accessInformation": "", "licenseInfo": "" }
